Development of Calibration and Verification Standards in Microstrip to 60 GHz

This paper discusses the development of microstrip standards for calibration and accuracy verification. Calibration standards for both OPEN-SHORT-LOAD and LRL are explored. The standards were developed for use in the newly developed Wiltron microstrip test fixture. Test data to confirm the quality of the calibrations is presented. Practical techniques for making multiport microstrip measurements without the need of special test fixtures are discussed.
